FEEDING MECHANISM.

Application filed April 26, 1915.

T all whom it may concern." I

Be it known that I, CAREY A. CHESHIRE, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Feeding Mechanisms, of which the following is a specification. I

My invention relates to improvements in feeding mechanisms especially adapted for use in connection with book gathering machines, the construction of the present application constituting in part that of my prior application for book gathering and stacking machines, filed February 20, 191%, Serial No. 819,925.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing forming a part of this specification, and in which,

Figure 1 is a plan view of a base plate equipped with mechanism embodying my invention, Fig. 2, an enlarged side view of a feed plate employed in the construction, Fig. 3, an enlarged section taken on, line 3-3 of Fig. 1, and Fig. 4, an enlarged transverse section taken on substantially line H of Fig. 1.

The preferred form of construction, as illustrated in the drawing, comprises areciprocating base plate made up of slats 5, 6, 7 and 8 secured together, as indicated, with longitudinal slots 8' between said slats, said base plate being especially designed for use in conjunction with the mechanism disclosed in my prior application, mentioned above, and serving to feed the bottommost member of a stack of book signatures from said stack onto a suitable traveling convever, or other receptacle, as will be readily understood by those skilled in this art. Adjustably mounted in each of the slots 8' is a feed plate or strip 9 having grooves 10 in its sides adapted to slidably embrace the edges of the slots 8, as indicated. At the rear end adjacent the bottom. each of the feed plates 9 is provided with a split 11 forming a spring clamping member 11. A clamping screw 12 is swiveled in the extreme rear end of each of the feed plates 9 and threaded in the corresponding clamping member 11 so as to be capable of springing said clamping member with respect to Specification of Letters Patent.

the body of the plate. A substantially triangularly shaped feeder stop or finger 13 is arranged on each of the feed plates 9 and provided with a pointed forward edge 14 and carried by a vertically slidable stem 15 slidable in the feeder plate 9. An adjusting screw 16 is threaded through each of the feeder plates 9 and locking member 11 immediately to the rear of feeder stop 13, and is provided with a circular head 17 operating in a corresponding opening in the rear portion of feeder stop 13, as indicated. Each of the screws 16 is provided with a flange 18 operating in a groove 19 formed in the corresponding feeder stop 13 to effect a swiveled connection therewith.-

By this arrangement it will be observed that by turning screw 16, the corresponding feeder stop may beadjusted relatively to the corresponding feeder plate and the top surface of the base plate, as desired. After such adjustment, the screw 12 is tightened thereby springing the looking or clamping member 11 to bind on the screw 16 and thus lock the same securely in adjusted positions. thereby springing the locking or clamping members 11' also contacts with the bottom of the adjacent bars 5, 6 and 8 to clamp said bars when screw 12 is tightened, as explained above, this arrangement thus also serving as a convenient means for securing the different feeder plates in adjusted positions in the slots 8.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation'and modification without depart ing from the spirit 'of the invention. ll, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. In combination a reciprocating member, two parallel screws in said member, one

of said screws being threaded in said mem-' of said screws being threaded in said member and the other swiveled therein; a stop operatively connected with said threaded screw; and a spring locking member formed integral with said member and threaded on both of said screws, substantially as described.

3. In combination a reciprocating member; two parallel screws in said member, one of said screws being threaded in said member and the other swiveled therein; a stop swiveled to said threaded screw and slidable in said member; and a locking member threaded on both of said screws, substantially as described.

4. In combination a reciprocating member; two parallel screws in said member, one of said screws being threaded in said member and the other swiveled therein; a stop swiveled to said threaded screw and slidable in said member; and a spring locking member formed integral with said member and threaded on both of said screws, substantially as described.

5. In combination a reciprocating plate;

two parallel screws in said plate; a stop swiveled to one of said screws and slidable in said plate; and a spring locking member formed integral with said plate and threaded on both of said screws, substantially as described.

6. The combination of a reciprocatin longitudinally slotted base plate; a fee plate grooved at its sides to embrace the edges of the slot in said base plate; two parallel screws in said feed plate; a spring clamping member' formed integrally with said feed plate by splitting the same and threaded on both of said screws and engaging said base plate; and a feed stop swiveled to one of said screws and slidable in said feed plate, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
